916177-72-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 916177-72-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,6,1,7 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 916177-72:
(8*9)+(7*1)+(6*6)+(5*1)+(4*7)+(3*7)+(2*7)+(1*2)=185
185 % 10 = 5
So 916177-72-5 is a valid CAS Registry Number.

Expanding dendrons. The photoisomerism of folded azobenzene dendrons
Gabriel, Christopher J.,Parquette, Jon R.
, p. 13708 - 13709 (2007/10/03)
Irradiation of a folded azobenzene dendron system triggers a large, reversible structural expansion. The dendrons adopt a compact helical conformation in the stable E form owing to the E geometry of azo linkage and the syn-syn preference of the dendritic
